This time, UFO fans are particularly excited because one of the scientists, Jennifer Eigenbrode, is described as an ‘astrobiologist’.

NASA is remaining characteristically tight-lipped, but has confirmed the announcement will feature ‘new science results from NASA’s Mars Curiosity Rover’.

NASA’s Curiosity Rover has explored the surface of Mars for five years, and has recently resumed drilling into rocks on the surface.

Has @NASA found life on Mars? The media advisory on Thursday's press conference on "new science results" from Curiosity rover states that results are embargoed by @sciencemagazine – and Eigenbrode's bio is suggestive. Watch this space (pun intended). #NASAhttps://t.co/k7CLi6MNSY

NASA says, ‘The media and public are invited to ask questions during a live discussion at 2 p.m. EDT Thursday, June 7, on new science results from NASA’s Mars Curiosity rover.’

The event will be streamed live worldwide on NASA television and via the space agency website.

NASA’s Jennifer Eigenbrode said in an interview this year, ‘I look at organic molecules in rocks, ice and sediments and try to figure out where they came from and what happened to them over time. I want to know their story. Are they from life?’
